Trainer options are activated using the NUMPAD on the right side of the
keyboard. You will need NUMLOCK 'On' for the hotkeys to works properly.
Laptop users may need to plug in a USB keyboard to get these keys.

One-Hit Kills: Allows you to kill enemies in one-hit. May not
work for all enemies or non-living opponents.

Ammo+Nades: This will also give you limitless secondary ammo
such as the grenades or energy blasts found in
some of the machine guns, though you may need to
gather some ammo normally before this will work.

Translocation: Turns your next bullet into a magic,
teleportation device. When you shoot an enemy
with it, you will take their place instantly.
Good for reaching weird and wonderful areas.

Low Grav: May not work on all levels or during some events!
This will also have the nice side-effect of big jump.

Friendly: This option will turn all enemies friendly to you!
If you are already in an enemies line of sight and
they are hostile towards you, just move out of sight
and back in, and they'll no longer pose a problem.

** TURN THE TOGGLE OPTIONS OFF WHEN NOT NEEDED, AND DON'T TRY TO
ACTIVATE ONES YOU DON'T NEED, OR WHEN OUT OF GAME. CARELESS
USAGE MAY RESULT IN UNWANTED SIDE-EFFECTS, SO BE WARNED!! **

* Also, due to the way the the games dynamically load certain files
which the trainer modifies, it may be safer to disable the options
between level loads/transitions, and re-enable the options as you
need them. This should eliminate any potential issues. *

if you cannot download trainer then go to Chrome/Firefox's settings, specifically to the Privacy settings and simply unchecking the "Enable phishing and malware protection" option.

Some Game Trainers are sometimes reported to be a Virus or Trojan,
the most common is a keylogger called HotKeysHook or the file
has been packed/protected with VMProtect or Themida and
is recognized as Win32/Packed.VMProtect or Win32/Packed.Themida.
In ALL cases this is a FALSE ALARM as NONE
of the Game Trainers @ GGMANIA contain known malicious code!!
